According to the 1851 census, William and Hanna and family were in Asphodel Twp, Peterboro Co. William J Brown is listed as having been born in Prince Edward, about 1820 (later information list birth date as 3 Feb 1820). Hanna was born in the US about 1826 (later information list her birth date as 26 Jan 1826). In the census two of their children were born in Athol, Albert Brown, born about 1843 (later information lists 12 May 1843) and Daniel Brown, born about 1845. William listed his occupation as blacksmith, although later censes lists either as farmer or blacksmith. I am unsure of Hanna's maiden name although in the 1870s and 1880s a Daniel Ferguson (born about 1804 in Canada) joins the family. One piece of information I have lists a marriage date as 3 Mar 1842, but does not list a location.
I am hoping that there are some records in Athol regarding the family, births and marriage. Thank you for any leads. I appreciate the help.
